AgateLib supports reading in resources (images, audio files, etc.) from an external XML file which identifies the resource files and their properties. There is code started for a Windows.Forms based editor to modify these resource files but it is very incomplete.

There is a similar Windows.Forms based code for making sprites. The goal for this code is to be able to trim off completely transparent rows and columns of pixels, so that only a minimal amount of data has to be stored in memory when loading sprites, which could lead to significant performance improvements at runtime.

There is also a font creator program which is mostly complete, but should be merged into the resource editor.

This task is a meta-task for these projects. If anyone is interested in working on these before I get around to it, please post here, in the forums, or PM me.
